Description: Differential Group Delay High TH
What is facilityPhysThresholdCapDifferentialGroupDelayHigh?
This OID stores the maximum high threshold for differential group delay (DGD) in the optical signal, measured in picoseconds per nanometer (ps/nm). Differential group delay causes pulse broadening and bit errors on high-speed links, especially coherent 100G/400G interfaces, requiring careful monitoring. A value of 50 ps/nm means you can set an alarm when DGD exceeds 50 ps/nm, triggering service quality alerts before data errors occur.
Examples
